CQLLAPSIBLE AND DEMOUNTABLE TIRE-RIM.-

specification of Letters Patent.

Application filed November 7, 1914. Serial No. 870,892.

This invention relates to collapsible and demountable tire rims, the object ,in view being to produce a rim of the character referred to which may be easily connected with and disconnected from the tire by inexperienced persons and which is collapsible in such a way that it may be folded compactly and conveniently carried in the machine in stead of on the resent day tire irons located on the running boards and at the back of the machine.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings z- Figure 1 is a side elevation of a portion of a wheel showing the demountable and collapsible rim of this invention applied thereto and also a ortion of a pneumatic tire. Fig. 2 is a si e elevation of the rim and tireon a reduced scale showing the manner of collapsing and spreading the rim. Fig. 3 a

1 4 is a erspective view of the rim per 8%. Fig. 5 is an enlarged fragmentary section showing one of the latches and the operating shaft therefor. Fig. 6 is a plan view of the same. p

Referring 'to the drawings A generally designates a wheel of the usual construction embodying the hub 1, spokes 2 and felly 3.

B generally designates the demountable and collapsible rim of this invention which is shown as comprising a plurality of arenate sections together forming in com le mental relation an annular rim adapts to carry, sup ort and hold a pneumatic tire 0.

Under tie arrangement shown in Fig. '2,"

the rim is composed of three sections 4, 5 and 6, said sections being connected together at their meeting extremities by means of hinges Z. To the outer extremity of each of the sections 5 and '6 is fixedly attached a hinge knuckle 8. One of said lmucklesis provided with a permanently attached hinge pin 9 while the other knuckle contains a rock shaft 10 provided at one end with an operating head 11. Intermediate its ends the shaft 10 has fast thereon one or more hook-shaped latches 12, the same being keyed to the shaft 10 as shown at 13 so as to be turned thereby when the shaft is operated by means of the thumb piece or head 11 for the purpose of moving the latch into and out of enga e ment with the pin 9 carried by the remainin knuckle 8 referred to.

Patented Mar. 2, 1M5.

ach of the rim sections t, 5 and 6 is,

shown as provided with the usual flan cs 14 to hold the ordinary clencher tire but it will means such as clamps 16 and bolts 11 may be employed for fastening the demountable rim on the felly 3.

From the foregoing description it will now be understood that in order to remove a rim from the tire, it is only necessary to turn the shaft 10 by means of the head 11 Suficiently to rock the latch or latches 12 out of engagement with the pin 9, this of course being done after the rim has been removed from the wheel. After the separable extremities of the rimhave thus been disconnected from each other, the sections 5 and 6 of the rim adjacent to such point of separation may be folded inwardly toward each other as indicated in Fig. 2 and this operation may be continued until all of the rimsections have been folded upon each other in compact relation. In order to do this, the rim sections 4, 5 and Gare preferably made of unequal len b so that the extremities thereof will not interfere with the folding operation. When completely scam the rim may be stored in a small space in a car.

In reassembling the tire and rim, the middle section 4 is first placed in engagement with the tire and thereafter the sections 5 and 6 are moved outwardly from each other f"? l i li i 1. A. collapsible vehicle wheel rim, enibodying a plurality of arcuate sections which collectively form "an annular rim structure,

seid sections being hinged together and each provided with tire holding means, one of the I connecting hinges comprising separable knuckles, e hinge-pin carried by one of-said knuckles, a shaft journaled in the other of said hinge knuckles, and a latch fast. on said shaft and movable thereby into and out gementwith said hinge pin.

V collapsible vehicle wheel .rim, embodying a plurality of arcuate sections which collectively forman annuiar rim structure, said sections being hinged together and each provided with tire holding means, one of the connecting hinges comprising separable knuckles, a hinge in carried by one of said knuckles, a sheft gotnrrnilled in the other of said hinge lmuckles,'a latch fast on said shaft and movable thereby into andout of engagement with said hinge pin and'an ope crating head on one end of said shaft.

In testimonv whereof I aflix in presence of two witnesses.
